DISPlay:TEXT:DATA <a> Define text message
This command defines the text message for display. A message can be as long as 12 char-
acters. A space counts as a character. Excess message characters results in an error. The
characters must be enclosed in either single quotes (‘ ’) or double quotes (“ ”).
DISPlay:TEXT:STATe ON | OFF Control (on/off) message for display
This command enables and disables the text message mode. When enabled, a defined mes-
sage is displayed. When disabled, the message is removed from the display.
A user defined text message remains displayed only as long as the instrument is in remote.
Taking the instrument out of remote (by pressing the LOCAL key or sending GTL) can-
cels the message and disables the text message mode.

All front panel controls (except LOCAL) are disabled. Normal display operation can be
resumed by using the ENABle command to enable the display or by putting the Model
2750 into local mode (press LOCAL).
